description PURPOSE:To make it unnecessary that a printed wiring board is connected to an outer lead part and to heighten reliability in connecting an inner lead part to an IC chip. CONSTITUTION:A wiring circuit 2 is arranged with a conductor on the surface of an insulating film 1 to form a film carrier 3. One end of the wiring circuit 2 is formed as an inner lead part 4 adhered to the surface of the insulating film 1. A bump is arranged on the surface of this inner lead part 4. The bump of the inner lead part 4 is connected to an electrode part of an IC chip 6 to mount the IC chip 6 on the film carrier 3. An outer lead part 7 formed on the wiring circuit 2 is connected to a receiving part 8, which is mounted on the film carrier 3.
